LUBRICATING MECHANISM FOR LOCOMOTIVES.

ans-mm I Specification of Letters Patent.

Patented Sept. 12, 1916.

Application filed January 3, 1916. Serial No. 69,738.

T 0 all whom it may concern Be it known that I, WILLIAM J. TREMAIN, acitizen of the United States, residing at Minneapolis, in the county ofHennepin and State of Minnesota, have invented a new and usefulImprovement in Lubricating Mechanism for Locomotives, of which thefollowing is a specification.

This invention relates to lubricating mechanism for cylinder valvechambers on steam engines, and is adapted for cooperation with boilerson locomotives or stationary steam plants or in other places.

The primary object of this invention 13 to force the oil positively intothe valve chambers, so that the parts of the valves and the workingsurfaces between the pretons and cylinders upon steam engines arethoroughly and etiiciently' lubricated.

In the accompanying drawings, I have illustrated the application of myinvention;

to a locomotive, but the invention is applicable to other types ofengines and boilers.

In the drawings, Figure 1 is a side elevation of a detail of alocomotive showing my invention applied thereto; Fig. 2 is a frontelevation of another detail; Fig. 3 is a section of a detail; Fig. I isa side elevation of a detail of an alternative construction; Fig. is anend view of a detail of the construction illustrated in Fig. 1, and Fig.6 is a longitudinal section of a detail of the construction illustratedin Fig. at.

In the drawing, A indicates a portion of the boiler of a locomotive, B adetail of the cab, C one of the cylinders, D one of the cylinder steamchests, E the steam duct leading from a source of superheated steam inthe boiler and F the usual lubricator, which is located in the cab. Thelubricator being of ordinary construction has the usual source of oilsupply and may be connected to a source of saturated steam by the pipe 2tapped into the boiler. 3 indicates one of the outlet pipes leading fromthe lubricator which usually is connected directly with the cylindersteam chest D. As the parts of the apparatus which lead to each or thecylinder valve chambers are similar, a description of one set willsuffice, it being understood that a similar set of devices is employedleading from the lubricator to each cylinder valve chamber. Arranged onthe casing 4 of the cylinder valve chamber valve chamber.

is a steam attachment G, the body of which is in the form of a tube 5having its lower end threaded into the wall of the valve casing and itsupper end coupled bythe bushing 6 with the lower end of the pipe 3,whereby oil from the lubricator is free to enter the chamber 7 in thetube leading downwardly into the cylinder valve chamber. The tube 5 .isformed with a branch 8, the passage therein being inclined downwardlyinto the tube toward the valve casing. Mounted within this downwardlyextending branch duct 9 is a nozzle 10, the reduced lower end of whichenters the chamber in the tube, so that its orifice 11 faces downwardlytoward the cylinder valve chamber. The upper end of the nozzle iscoupled with a steam pipe l2.by means of a bushing 13, said pipe beingtapped into the duct 14 leading from a source of superheated steamsupply inthe boiler A. The size of the orifice 11 and the pipes leadingfrom the lubricator and source of superheated steam supply are,proportioned, so

that a jet of superheated steam will automatically and positivelyproject the oil which is forced by the lubricator through the pipe 3downwardly into the cylinder In the alternative construction theattachment H which is of modified. form is located near the lubricatorand is operated by saturated steam instead of superheated steam, thesupply of saturated steam being admitted into the attachment'through thehand operable valve 20. The nozzle 21 through which the saturated steamis forced, projects a jet of steam longitudinally through the passagewhich is connected by the pipe 23 with the cylinder steam chest D. Thebranch 2% which extends into the chamber 25 of the attachment; atsubstantially right angles to its longitudinal axis admits the oil fromthe supply pipe 26 leading from the lubricator F. The lubricator F is ofsubstantially the same construction as that illustrated in Fig. 1, itbeing connected by the pipe 27 with a supply of saturated steam receivedfrom the boiler. A similar set of devices is employed for each cylinderas in the preferred construction. In operation the lubricating oil whichis forced downwardly from the lubricator F enters the attachmentimmediately loackof the orifice of the nozzle. The saturated steam whichblows through the nozzle catches the oil and projects it forwardly andcauses it to enter the cylinder valve chamber positively through thepipe 23.

In accordance with the patent statutes I have described the principlesof operation of my invention, together with the apparatus which I nowconsider to represent the best embodiment thereof, but I desire to haveit understood that the construction shown is only illustrative, and thatthe invention can be carried out by' other means and applied to usesother than those above set forth within the scope of the followingclaims.

Having described my invention, what I claim as new and desire to protectby Letters Patent is:

1. Lubricating mechanism, comprising, in combination with a cylindervalve chamber and an oil feed, an attachment comprising .a casing formedwith a main passage and a branch passage, an end of one of said passagesbeing connected with said oil feed to receive lubricating oil therefrom,and the other end of the passage opposite said oil receiving passagebeing connected with said cylinder valve chamber, a nozzle arranged inthe other of said passages having its inlet directly connected with asource of superheater steam supply and its orifice directed forwardly toproject the oil from said feed supply positively toward and into saidcylinder valve chamber.

2. Lubricating mechanism, comprising, in combination with a cylindervalve chamber on a locomotive and an oil feed in the cab of saidlocomotive, an attachment comprising a casing formed with a main passagedirectly connected with said oil feed to receive pure lubricating oiltherefrom and with said valve chamber and a branch passage inclinedforwardly into said main passage toward said valve chamber, a nozzle insaid branch passage extending forwardly into said main passage andhaving itsorifice directed forwardly to force oil from said main passagedirectly into said valve chamber and a source of superheated steamsupply with which the inlet of said nozzle isconnected, whereby oil isprojected automatically by a jet of superheated steam is- Gopies of thispatent may be obtained for five cents each, by addressing the suing fromsaid orifice into said valve chamber.

3. A lubricating device for superheater locomotives provided with an oilfeed and a cylinder valve chamber, an attachment comprising a casingformed with a main and a branch passage opening therei'nto to deliver atthe same point into said chamber, a direct connection between said oilfeed and one of said passages, and a connection between the superheatersteam supply and the other of said passages for projecting by a forcefeed action the lubricantinto said chamber.

4. The combination with a superheater "locomotive having an oil feed anda cylincating with said chamber and located in proximity to said feedconnection, a direct feed connection between said oil feed and saidcasing, and means directly connecting said superheated steam supply withsaid casing for projecting the lubricant from said oil feed into saidcasing.

6. The combination with asuperheater locomotive having an oil feed and acylinder valve chamber directly fed from the superheated steam supply,of a casing communicating with said chamber and located in proximity tosaid feed connection, a direct feed connection between said oil feed andsaid casing, and means connecting said superheated steam supply withsaid casing for automatically projecting the lubricant from said oilfeed into said casing.

In testimony whereof, I have signed my name to this specification.
